l This invention relates to the hatchway construction of a metal carroof, particularly hatch constructions of the type wherein a metal hatchframe hasl an uninsulated upper portion disposed above the general levelof the roof and closed by an uninsulated lid and a lower portiondisposed below said level and forming a tapered seat for an insulatedplug.

l The invention has for its principal object to simplify such a hatchconstruction bydispensing with the separate tapered heat insulated plugAand the special tapered seat heretofore commonly required. Anotherobject is to provide a preassembled heat insulated hatch frame and car-*line assembly adapted for application to the car as a complete unit.Other objects are simplicity, cheapness and durability of construction.The invention consists in the hatch construction and in the parts landin the combinations and arrangements of parts hereinafter described andclaimed.

In the accompanying drawings which form part of this specification vand.wherein like symbols refer to like parts wherever they occur.

o Fig. 1 is a plan view of the end portion of a metal car roof providedwith a hatch construction embodying my invention;

Fig. 2 is a vertical partial cross-section thereof on the line 2 2 inFig. 1;

Fig. 3 is a vertical partial longitudinal section on the line 3-3 inFig. 1;

Fig. 4 isan enlarged fragmentary section similar to Fig. 2 through oneside of the hatch construction;

Fig. 5 is an enlarged fragmentary section similar to Fig. 3 through oneside of the hatch construction; and Figs. 6, '7, 8 and 9 are viewssimilar to Fig. 5 illustrating five modified forms of hatchconstruction.

The metal car roof illustrated in the accompanying drawings comprisesend and intermediate roof sheets I and 2, respectively, that extend fromside plate 3 to side plate 3 of the car with their eaves ends supportedon and riveted or otherwise secured to the outstanding top flanges ofeaves anglesy #,whose depending anges are riveted orotherwise rigidlysecured to the upstanding inner side anges of said side plates. The '50end and intermediate roof sheets are provided along theiradjacentmargins' with upstanding flanges'i that are straddled by a seamlcap 6 that s is riveted or otherwise secured to said flanges and tothetop flanges of the eaves angles l. lAt the end of the car, the endsheet I is supported on straight', from top to bottom of said frame.Said the general level of the end roof sheet where it and riveted orotherwise secured to the outstanding top flange of an end angle 1, whosedepending ange is riveted or otherwise secured to the outstanding topflange of a metal end plate la.

As shown in Fig. 1, the roof is provided with one 5 or more hatchwaysthat lead downwardly into the interior of the car through the end roofsheet I and a framework located therebelow. Said framework comprisesspaced parallel frame or carline members 8, which extend from side plate10 to side plate of the car with their ends rigidly secured thereto bysuitable brackets 9, and spaced parallel cross frame members I0 that aresecured to and flush with the tops of said carlines and cooperatetherewith to denne the hatchway open- 15 ing in said framework. As shownin Figs. 1 to 5, the carlines comprise metal angles disposed with oneflange up and facing outwardly, and the A cross members I0 are in theform of flat plates that cooperate with said flanges to form acontinuous supporting surface around the hatchway opening in saidframework.

Mounted in the hatchway opening defined by the carlines 8 and crossplates Ill is a metal hatch frame having parallel side walls that extendframe extends downwardly through said opening with its carline engagingsides secured to the carlines preferably 4by welds I2 that extend alongthe lower edges of said carlines and with its two other sides 'securedto the cross plates I0 preferably by welds I3 that extend along thebottoms of said plates at the inner edges thereof. Said metal hatchframe also extends upwardly above is provided immediately above thecarline members and cross members with an exterior downwardly openinghollow rim portion I4 formed by a flange that extends outwardly from theupper end of said frame and thence downwardly and outwardly at an anglethereto with its lower end located adjacent to the outer edges of saidmembers.

The endif-roof sheet I is provided above the opening defined by theframe members 8 and I0 45 with a hatch opening of substantially the samesize and shape as the rimv portion I4 of the metal hatch frame II, andanv upstanding ange` iiiA along the margin of said hatch opening `thatbears against the outer face of the depending outer wall of said rimportion with its upper edge rigidlysecured thereto preferably by meansof a weld I6 of added metal that extends continuously along the top edgeof said ange. The metal hatch frame Il is closed by means of a members.

suitable lid or cover I1 that rests upon the top of the hollowrimportion I4' of said hatch frame and is provided with a suitable heatinsulating material I8. The hollow rim portion I4 ofthe hatch frame isalso provided with a iiller of any suitable heat insulating material I9.

In the constructions illustrated in Figs. 6 and '7, the outer wall ofthe hollow rim portion 20 of the hatch frame is spaced from the outeredges of the carline members and cross-members to provide an opening 2|through which a loose, fibrous heat insulating material 22 may beinserted either before or after the hatch and carline assembly isapplied to the car. In the constructhe hollow rim portion of the hatchframe are formed by a separate member 23 of angle-shaped section whoseupper ange is secured by a weld to the upper end of the main bodyportion of saidhatch frame.

In the construction illustrated in Fig. 8, angle shaped carline membersandcross members form the lower portion of the hatch frame; and thehollow upper rim portion thereof is formed by an inverted channel-shapedmember 24 which rests on and is closed by the lateral top flanges ofsaid The inner wall of the rim member 24 may be welded, as at 25, to thecarline and cross members; and the outer wall of said rim is disposedparallel to said inner wall, instead of being serves to'prevent leakagetherebetween and tor prevent movement of said sheet relative to thehatch frame.

material may be used as a ller for the hatch frame rim and held undercompression thereby..

A rinrller of wood or rigid insulation material lmay also be used tostiffen and strengthen the hollow hatch frame rim.

The construction hereinbefore described has several advantages. Theportion of the hatch frame located above the general roof level isinsulated and is closed by an insulated cover, thereby materiallyreducing the transfer of heat through said portion and said cover intothe interior of the hatch frame and thus dispensing with the separatetapered heat insulated plug and the tapered seat heretoforerequiredtherefor in the hatch frame. The carline and crossframe members of thecombined carline assembly and hatch frame supports serve to stiifen' andstrengthen the hatch frame rim and to retain the filler of insulation orother material therein. The complete carline and insulated hatch frameassembly may be assembled off the car and furnished for application tothe car as a complete, preassembled unitary structure.
